When we think celebrity cars, we largely think of one of two things; supercars and massive SUVs. In either case, efficiency is not for the taking. Reality though paints a much different picture, and if we pay attention to The Sunset Strip, we could see a few smaller, eco-friendly rides weaving through traffic with the Aston Martins and Escalades. Hollywood is known for its “slacktivist” causes, but when it comes to eco-friendly motoring, there are a few out there who are the real deal. Here are six:

Jay Leno – Chevy Volt

When it comes to cars in Hollywood, Jay Leno is amongst the best of the best, sporting one of the most prolific private car collections in the country. When EVs hit the consumer market, Leno jumped in with both feet and has driven nearly every one on the market. His electrified ride of choice however, has remained the Chevy Volt.

George Clooney – Tesla Roadster

Like Leno, George Clooney buys domestic, but opts for a bit more performance with his $100,000 + Tesla Roadster. Clooney is in good company though, as the Roadster seems to be the EV of choice for quite a few A-Listers; Matt Damon, Anthony Kiedis, and Will.i.am have all been spotted driving the high-performance coupe around Hollywood. Not to be left out, Jay Leno also sports one of these beasts in his collection.

Sir Paul McCartney – Lexus LS600h

An eco-friendly car literally fit for a Knight, the LS600h is powered by a gargantuan 5 liter V8 engine with the assistance of two electric motors, and according to Edmunds, it barely sees better mileage than the non-hybrid LS. So then what makes this car suitable for environmental activist Sir Paul McCartney? The Super Ultra Low Emissions Vehicle rating. Sir Paul McCartney’s car collection is definitely impressive.

Leonardo DiCaprio – Fisker Karma

Leo has been a green vehicles’ advocate since 2008 when he was chauffeured to the Oscars in a Toyota Prius. He’s since been featured in a marketing campaign by Elon Musk’s Tesla Motors, but owns a Karma himself. Other famous owners past and present include Al Gore, Ashton Kutcher, Matt Damon and Justin Bieber, who received one from his manager as an 18th birthday gift.

Alyssa Milano – Nissan Leaf

Besides Alyssa Milano, Samantha Micelli actually owns two EVs: the Nissan Leaf and the Chevy Volt. The former teen-idol says that she was compelled to go green in the wake of the Deep Horizon oil disaster a few years back. Lance Armstrong, was also one of the first U.S. customers for the Leaf.

Larry David – Toyota Prius

One of TVs most successful writers/creators/producers of all time, Larry David has a net worth somewhere in the high 100 millions, but still sports his Prius. David’s fictionalized self drives the car on Curb Your Enthusiasm, and so does the real-life Larry. A known environmental advocate along with his former wife Laurie, David was one of Hollywood’s earliest adapters to green motoring. He is hardly alone however, as the Prius has the Hollywood following one would expect of the first commercially viable hybrid cars to hit the U.S. market. Emily Blunt, Cameron Diaz, Julianne Moore, Natalie Portman, Jennifer Aniston, Bradley Cooper, Adrian Grenier, Dustin Hoffman, Harrison Ford, and Tom Hanks have all been seen driving one around.
